Before plans, know what your lot can actually do.

An ADU can become a rental unit, guest house, family suite, home office, or long-term property upgrade. The first step is checking the property, access, structure, goal, and permit path.

ADU Options

The right ADU depends on the property.

IL Total helps San Diego homeowners compare the practical options before committing to full plans.

01

Detached ADU

A separate backyard unit for rental income, family, guests, or long-term flexibility.

02

Garage Conversion

Turn an existing garage into a legal living space when the structure and layout make sense.

03

Attached ADU

A unit connected to the main home, planned around the existing layout and property access.

04

Junior ADU

A smaller living unit created within part of the existing home for compact, practical use.

Why One Team Matters

ADU projects get expensive when the hand-offs are messy.

A designer, permit path, and builder can all be right on paper but disconnected in practice. IL Total keeps those decisions connected from the first conversation.

The common problem

  • Plans are created before build readiness, budget, and site conditions are clear.
  • Bad permit prep can slow the project down and bring costs up.
  • The contractor faces issues after plans are already complete.
  • You become the unpaid project manager, spending more time chasing answers.

The IL Total path

  • Feasibility is reviewed before full plans.
  • Design, permit, and build decisions stay connected.
  • The next step is clarified before you commit.
  • One local team stays responsible, with little to no involvement needed on your side.
